    “SSLV-D1 placed the satellites into 356 km x 76 km elliptical orbit instead of 356 km circular orbit. Satellites are no longer usable. Issue is reasonably identified. Failure of a logic to identify a sensor failure and go for a salvage action caused the deviation,” ISRO said in an update on its official Twitter handle.

    It added a detailed statement by ISRO Chairman S Somanath will be “uploaded soon.”

    In its maiden SSLV mission, the launch vehicle carried The Earth Observation Satellite EOS-02 and the co-passenger student satellites AzaadiSAT.

    SSLV had suffered ‘data loss’ in its terminal stage, after performing “as expected” in all stages. It had earlier after lifted off from the spaceport here on Sunday morning.

  • India’s new rocket SSLV lifts-off with earth observation satellite

    By IANS

    SRIHARIKOTA: India’s brand new rocket Small Satellite Launch Vehicle (SSLV-D1) on Sunday morning lifted off with an earth observation satellite-02 (EOS-02) formerly known as Microsatellite-2 weighing about 145 kg.

    Piggybacking on that was the eight kg AZAADISAT built by 750 students of government schools facilitated by SpaceKidz India.

    At about 9.18 a.m. the 34-metre tall and 120-ton rocket broke free of the first launch pad and started its maiden upward one-way journey carrying the two satellites.

    The rocket with a thick orange flame at its tail slowly gathered speed and went up and up.

    Just over 12 minutes into its flight, the SSLV-D1 will put into orbit the EOS-2 satellite and a few seconds later the AZAADSAT will be orbited.

    According to the ISRO, the SSLV is a ready-to-transfer rocket with modular and unified systems with standard interfaces for production by the industry.

    The SSLV design drivers are low cost, low turnaround time, flexibility in accommodating multiple satellites, launch-on-demand feasibility, minimal launch infrastructure requirements and others, ISRO said.

    The commercial arm of ISRO, NewSpace India Ltd plans to transfer the SSLV technology for production in the private sector.

    The Indian space agency said the EOS-02 satellite is an experimental optical imaging satellite with high spatial resolution. The objective is to realise and fly an experimental imaging satellite with short turnaround time and showcase launch-on-demand capability.

    The new technologies realised for the Microsat series of spacecrafts include payloads with a common fore optics and metallic primary mirror realised with the limited mass and volume of Microsat Bus, ISRO said.

    With the new launch vehicle included in its product lineup, ISRO will have three rockets — Polar Satellite Launch Vehicle (PSLV) and its variants (cost about Rs 200 crore), Geosynchronous Satellite Launch Vehicle (GSLV-MkII cost about Rs 272 crore and Mk III Rs 434 crore) and SSLV (Development cost of three rockets about Rs 56 crore each) and production cost may go down later.

    According to SpaceKidz India, the significance of this project is that it has been conceptualised as a tribute to mark the 75th anniversary of Independence.

    “From 75 government schools for girls across India, we have selected 10 students to give this opportunity. The selected students are predominantly from Classes 8-12. This is a first-of-its-kind Space mission with an ‘All women concept’ to promote women in STEM as this year’s UN theme is ‘Women in Space’,” SpaceKidz India said.

    Niti Aayog has partnered for this project to bring this opportunity to students of the government girl schools across India.

  • ISRO’s SSLV lifts-off with student satellite AzaadiSAT then reports ‘data loss’ at terminal stage

    By PTI

    SRIHARIKOTA: ISRO Chairman S Somanath on Sunday informed the space agency’s maiden Small Satellite Launch Vehicle (SSLV) suffered “data loss” at the terminal stage, although three stages “performed and separated,” and said the space agency was analysing the data to ascertain the status of the vehicle and the satellites.

    SSLV-D1/EOS 02 was carrying an earth observation satellite and a student satellite.

    “All stages performed as expected. The first stage performed and separated, second stage performed and separated, the third stage also performed and separated, and in the terminal phase of the mission, some data loss is occurring and we are analysing the data and we will come back on the status of the satellites as well as the vehicle performance soon,” Somanath said from the Mission Control Centre here, minutes after the launch vehicle lifted off from the spaceport.

    “We are currently in the process of analysing the data to conclude on the final outcome of the mission with respect to stable orbit achieved or not, please wait and we will come back,” he added.

    A jubilant mood in the Mission Control Centre soon made way to anxiety, before Somanath updated about the mission status.

    The Indian Space Research Organisation (ISRO) embarked on its maiden small satellite launch vehicle (SSLV) mission, carrying earth observation satellite EOS-02 and co-passenger students satellite AzaadiSAT on Sunday.

    The SSLV-D1/EOS-02 mission by the Indian space agency is aimed at garnering a larger pie in the small launch vehicles market, as it can place the satellites into Low Earth Orbit.

    At the end of a seven-and-a-half-hour countdown, the 34-metre-long SSLV soared majestically at 9.18 am amid cloudy skies to place the satellites into the intended orbit.

    The EOS-02 is an experimental optical remote sensing satellite with a high spatial resolution.

    It is to realise and fly an experimental imaging satellite with a short-turnaround time and to demonstrate launch-on-demand capability.

    EOS-02 belongs to the microsatellite series of space crafts.

    The AzaadiSAT is a 8U Cubesat weighing around 8kgs.

    It carries 75 different payloads each weighing around 50grams.

    750 girl students from rural regions across the country were provided guidance to build these payloads.

    The payloads are integrated by the student team of ‘Space Kidz India’.

    The ground system developed by ‘Space Kidz India’ will be utilised for receiving the data from this satellite, ISRO said.

  • History beckons ISRO with maiden SSLV-D1/EOS-2 mission on August 7

    By PTI

    CHENNAI: The Indian Space Research Organisation (ISRO) is on the cusp of making history as the space agency is all set to embark on its maiden SSLV mission, ferrying an earth observation satellite and a student satellite from the spaceport in Sriharikota, about 135 kms from here on Sunday.

    After carving a niche on successful mission launches through its trusted workhorse Polar Satellite Launch Vehicles (PSLV), Geosynchronous Launch Vehicle (GSLV), ISRO would be making its maiden launch of a Small Satellite Launch Vehicle (SSLV), which would be used to deploy satellites in the low orbit earth.

    Scientists at the ISRO have been engaged in developing small launch vehicles over the last few weeks to meet the demand for such small satellites, which weigh upto 500 kgs and can be injected into the 500 kms low earth orbit.

    The SSLV is 34m tall, about 10m less than the PSLV and it has a vehicle diameter of two metres as compared to 2.8 metres of PSLV.

    SSLV has a lift off mass of 120 tonne while PSLV has 320 tonnes, which can carry payloads upto 1,800 kgs.

    On Sunday’s mission, SSLV would carry Earth Observation Satellite -02 and a co-passenger satellite AzaadiSAT — developed by the student team of ‘Space Kidz India’.

    The launch of the SSLV-D1/EOS-02 Mission is scheduled for Sunday, August 7, 2022, at 9:18 am (IST) from Satish Dhawan Space Centre (SDSC), Sriharikota.

    According to ISRO sources, the countdown compared to other missions which would be 25 hours is reduced to five hours and was expected to commence on Sunday at 4.18 hours for the lift-off scheduled at 9.18 am from the first launch pad at Satish Dhawan Space Centre, Sriharikota.

    The significance of SSLV is that it has the fourth stage which carries liquid propulsion-based Velocity Trimming Module to place the satellites into the intended orbit.

    The rocket comprises solid fuel to fire the first three stages.

    The Earth Observation Satellite designed by ISRO, offers advanced optical remote sensing operating in an infra-red band with high spatial resolution.

    It belongs to the micro-satellite series of spacecraft.

    After travelling for about 13 minutes, SSLV is expected to first place the EOS-02 into the intended orbit followed by AzaadiSAT which is an eight kg Cubesat designed by the girl students from government schools across the country to mark the 75th Anniversary of Independence.

    ISRO said, SSLV offers low turn-around time, flexibility in accommodating multiple satellites, launch on-demand feasibility and minimal launch infrastructure requirements.

    The ground system developed by Space Kidz India would be utilised for receiving the data from this satellite.

    ISRO began launching sounding rockets in 1965 to probe the upper atmospheric regions and for space research.

    The first sounding rocket was launched near Thiruvananthapuram in November 1963.

    The space agency later in 1980 launched the country’s first Satellite Launch Vehicle -3 which can carry payloads of upto 40kgs.

    In 1987, ISRO conducted the first developmental flight of Augmented Satellite Launch Vehicle (ASLV) with a payload capacity of upto 150kgs.

    Later, ISRO made its first Polar Satellite Launch Vehicle in September 1993, which was unsuccessful.

    However in 1994, ISRO tasted success on the first successful launch as it emerged to be a reliable and versatile trusted workhorse.

    ISRO conducted the first flight of the Geosynchronous Satellite Launch Vehicle in 2001 which is the largest launch vehicle developed by India, currently under operation.

    The GSLV has a lift-off mass of 414.75 tonne.
